. The knife is shown in detail in fig. 3.

The square a. of its shank is provided with a ferrule, D, which has ribs, 12, fitting in the rebate d of the stock A, as seen by ,dotted lines in fig. 2, so as \to make the knife adjustable in any part of the stock, whereby the latter may be equally balanced in cutting narrow strips of leather, thus overcoming the difficulty usually experienced by having the knife stationary.

The ferrule is shown in detail in figs. 4 and 5.

The round part 0 of the knife-shank is provided with a nut, j; which is made fast in the handle, E, as represented by dotted lines in fig. 1, so that, by taking hold of the handle with one hand and the stock 1 with the other, theknife may be loosened for adjustment at any part of the stock A, and-then secured by a reversed motion of the hand.

The adj ustable guide 0 has a slide, 9, seen in fig. 6, that fits in the slot h of the stock A, so as to make the guide adjustable at any point desired.
